-3(-3)^2 = -27

-3(9) = -27

-27 = -27

The answer would be -9/11 because since the denominator is the same, we can ignore it for now. Just add -4 and -5, you get -9. Finally, add the denominator of 11 back to get the answer

Answer:

The answer is A.

Step-by-step explanation:

To convert a mixed number to its lowest form, one needs to change the mixed number into an improper fraction and then reduce this improper fraction to the lowest possible fraction. To do these conversions, one needs to perform a few calculations. One also has to understand the definitions of "mixed number," "improper fraction" and "proper fraction."

A proper fraction is a fraction that has a lower number in the numerator and a higher number in denominator, such as the fraction three-fourths. An improper fraction is the inverse of this, which entails the higher number in numerator and lower number in the denominator, like 5/3. A mixed number is a whole number with a fraction, such as 1 3/4.

To convert the mixed number 1 3/4, one has to multiply the denominator 4 by the whole number 1 that gives 4, add this 4 to the 3 in the numerator to get 7 and place 7 over the denominator to find the improper fraction 7/4. In this case, this is the lowest form for this mixed number. However, if the mixed number is 6 4/6, then this converts to the improper fraction 40/6. One can divide the numerator and denominator of 40/6 by 2 to find that 20/3 is the lowest form for the mixed number 6 4/6.To convert a mixed number to its lowest form, one needs to change the mixed number into an improper fraction and then reduce this improper fraction to the lowest possible fraction. To do these conversions, one needs to perform a few calculations. One also has to understand the definitions of "mixed number," "improper fraction" and "proper fraction."

Step-by-step explanation:

just did the lesson

The distance between -15 and 20 on the number line is 35 units, calculated by taking the absolute difference between the two numbers.

The distance between two points on a number line can be found by taking the absolute difference between those points. To find the distance between -15 and 20, you subtract the smaller number from the larger one and take the absolute value:

|20 - (-15)| = |20 + 15| = |35| = 35

Therefore, the distance between -15 and 20 is 35 units.

Shirley/Tracey has to stay at least 10 days for the M and N to cost less

Answer:

10 days.

Step-by-step explanation:

Let d represent number of days.

We have been given that ABC Travel offers a plane ticket for $295 and a rental car for $39 per day. The total cost of travelling x days using ABC travel company would be [tex]39x+295[/tex].  

We have been given that M and N Travel offers a plane ticket for $350 and a rental car for $33 per day. The total cost of travelling x days using M and N travel company would be [tex]33x+350[/tex].

To make M and N travel the better deal, we will set an inequality, where total cost of x days using ABC travels is greater than M and N travels as:

[tex]39x+295>33x+350[/tex]

[tex]39x-33x+295>33x-33x+350[/tex]

[tex]6x+295>350[/tex]

[tex]6x+295-295>350-295[/tex]

[tex]6x>55[/tex]

[tex]\frac{6x}{6}>\frac{55}{6}[/tex]

[tex]x>9.166[/tex]

Since the closest integer to 9.1677 is 10, therefore, for a vacation of 10 days using M and N travels will be the better deal.

For this question, just multiply the number (300) by the percent (.95)

Your answer is 285 women

To determine the number of women with babies in good or excellent health, we multiply the total number of women (300) by the percentage of women with healthy babies (95%). We find that 285 out of the 300 women had babies in good or excellent health.

In the study mentioned, it is stated that 95% of pregnant women with good to excellent health diets had babies in good or excellent health. The total number of women considered in this study is 300. To calculate the exact number of women who had babies in good or excellent health, we can apply the concept of percentage which means 'per 100'. So, 95% of 300 women equals (95/100)*300 = 285 women. Therefore, out of 300 women, 285 women had babies in good or excellent health.

Final answer:

A counterexample is an example that disproves a statement or argument by showing that the conclusion can be false even when the premises are true. This concept is widely used in philosophy to test and refine arguments and definitions.

Explanation:

A counterexample is a specific case or example that refutes a general assertion or proposition. In philosophical reasoning and critical thinking, counterexamples hold particular significance as they can demonstrate the invalidity of an argument. The argument may have premises that are all true, but the conclusion drawn from these premises is shown to be false through the counterexample. Philosophers often use this method to refine definitions, understand the essence of concepts, and advance epistemological theories about knowledge and justification. Furthermore, it is a useful practice to generate counterexamples in order to test the validity of our own beliefs and arguments.

To identify counterexamples, one must consider a statement or argument and then conceive of a scenario where despite the premises being true, the conclusion does not follow. This act of finding counterexamples is critical for ensuring the soundness of deductive reasoning and often leads to the revision or abandonment of flawed concepts or arguments.

The first equation is open, since it has an unsolvable variable. 1x could be anything!

The second equation is false, because 20 - 11 = 9    not 11.

The last equation is true,  7 + 10 does equal 17!

1x + 4 = 10

x = 10 - 4

x = 6 (true)

--------------------

20 - 11 = 11

20 - 11 = 9 (false)

Final answer:

To find the distance from Checkpoint B to the starting line, we add the distances from Checkpoint B to Checkpoint A and then double that sum.

Explanation:

To find the distance from Checkpoint B to the starting line, we need to add the distances from Checkpoint B to Checkpoint A and then double that sum. Let's calculate it step by step:

Distance from starting line to Checkpoint A: 20 yards

Distance from Checkpoint A to Checkpoint B: 12 yards

Total distance from starting line to Checkpoint B: 20 + 12 = 32 yards

To find the distance from Checkpoint B to the starting line, we double the distance from starting line to Checkpoint B: 2 × 32 = 64 yards

Therefore, the distance from Checkpoint B to the starting line is 64 yards.

Answer: The values of the function V(x) over the domain (2, 5, 7) are 17881.66, 12,606.01 and 9985.224.

Explanation:

The cost of car is $22575 and the value of car depreciate at a rate of 11% per year.

The value of car can be modeled by the equation,

[tex]V(x)=22,575(0.89)^x[/tex]

Where is number of years after purchase of car or the age of car. We have to find the value of the function over the domain (2,5,7), so put x=2,

[tex]V(x)=22,575(0.89)^2=17881.66[/tex]

It means the value of car will be $17881.66 after two years.

put x=5,

[tex]V(x)=22,575(0.89)^5=12,606.01[/tex]

It means the value of car will be $12,606.01 after five years.

put x=7,

[tex]V(x)=22,575(0.89)^7=9985.224[/tex]

It means the value of car will be $9985.224 after seven years.

Answer:

x < -19/13

Step-by-step explanation:

The solution to the inequalities −9x+2>18 and 13x+15≤−4 is to find values of x that satisfy either x < ∘⅗⁄3 or x ≤ ∘⅗/13.

To solve the equations −9x+2>18 OR 13x+15≤−4, we need to treat them separately as two different inequalities.

For the first inequality, subtract 2 from both sides to get −9x > 16, then divide by −9 to isolate x, which gives us x < ∘⅓⁄9 or x < ∘⅗⁄3.

For the second inequality, subtract 15 from both sides to get 13x ≤ −4 − 15 or 13x ≤ −19. Finally, divide by 13 to isolate x, leading to x ≤ −⅓⁄13 or x ≤ ∘⅗/13.

Therefore, the solution to the system of inequalities is any x that satisfies at least one of these conditions: x < ∘⅗⁄3 or x ≤ ∘⅗/13.

C. √3 + 5.5 = 7.2320508...

D. π + √2 = 4.55580..

Rational numbers are any fractions, integers, terminating decimals, or repeating decimals.

Option B will be a rational number while options A, C and D will be irrational numbers.

A number that can be written in p/q form where q≠0 is called a rational number.

An irrational number is non-terminating and non-repeating in nature.

For example, π is an irrational number because

π =3.1415926535897.....................that is non-terminating and non-repeating and can never be written in p/q form

Similarly, a non-perfect-square number written inside a root is also an example of an irrational number.

A)  π + 18

π is an irrational number while 18 is a rational number so the sum of irrational and rational will be an irrational number.

B) √25 + 1.75

√25 = 5 i.e. a rational number

1.75 is a rational number

Rational + Rational = Rational

5+1.75 = 6.75

6.75 is a rational number.

C) √3 + 5.5

√3 is an irrational number so √3 + 5.5 is an irrational number.

D) π + √2

π is an irrational number so π + √2 is an irrational number.

Hence, Option B will be a rational number while options A, C and D will be irrational numbers.
